it mildly.C)As I was suffering through my week of anxiety,overthinking the material and guessing my grasp of it,I didsome of my own polling among students and professors.David Eisenbach,who teaches a popular class on U.S.presidents at Columbia,prefers the in-class variety.He believes students ultimately learn more and encouragesthem to form study groups.That way they socialize over history outside the class,which wouldnt happenwithout the pressure of an in-class exam,he explained.Furthermore,in-class exams force students to learnhow to perform under pressure,an essential work skill.D)He also says there is less chance of cheating with the in-class variety.In 2012,125 students at Harvard werecaught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitledIntroduction To Congress.Some colleges have what they call an honor code,though if you are smartenough to get into these schools,you are either smart enough to get around any codes or hopefully,too ethical toconsider doing so.As I sat blocked and clueless for two solid days,I momentarily wondered if I couldnt justcall an expert on the subject matter which I was tackling,or someone who took the class previously,to get megomg.E)Following the Harvard scandal,Mary Miller,the former dean of students at Yale,made an impassioned appealto her schools professors to refrain from take-home exams.Students risk health and well being,as well asperformance in other end-of-term work,when faculty offers take-home exams without clear,time-limitedboundaries,she told me.Research now shows that regular quizzes,short essays,and other assignments overthe course of a term better enhance learning and retention.F)Most college professors agree the kind of exam they choose largely depends on the subject.A quantitative-basedone,for example,is unlikely to be sent home,where one could ask their older brothers and sisters to help.Vocational-type classes,such as computer science or journalism,on the other hand,are often more researchoriented and lend themselves to take-home testing.Chris Koch,who teaches History of Broadcast Journalismat Montgomery Community College in Rockville,Maryland,points out that reporting is about investigation ratherthan the memorization of minute details.In my field,its not what you knowits what you know how to findout,says Koch.There is way too much information,and more coming all the time,for anyone to remember.I want my students to search out the answers to questions by using all the resources available to them.G)Students test-form preferences vary,too,often depending on the subject and course difficulty.I prefer takehome essays because it is then really about the writing,so you have time to edit and do more research,saysElizabeth Dresser,a junior at Barnard.Then there is the stress factor.Francesca Haass,a senior at Middlebury,says,I find the in-class ones are more stressful in the short term,but there is immediate relief as you swallowinformation like mad,and then you get to forget it all.Take-homes require thoughtful engagement which canlead to longer term stress as there is never a moment when the time is up.Meanwhile,Olivia Rubin,asophomore at Emory,says she hardly even considers take-homes true exams.If you understand the materialand have the ability to articulate(说出）your thoughts,they should be a breeze.H)How students ultimately handle tests may depend on their personal test-taking abilities.There are people whoalways wait until the last minute,and make it much harder than it needs to be.And then there are those who,not knowing what questions are coming at them,and having no resources to refer to,can freeze.And then thereare we rare folks who fit both those descriptions.I)Yes,my advanced age must factor into the equation(等式），in part because of my inability to access theinformation as quickly.As another returning student at Columbia,Kate Marber,told me,We are learning notonly all this information,but essentially how to learn again.Our fellow students have just come out of highschool.A lot has changed since we were last in school.5欢迎您阅读并下载本文档，本文档来源于互联网，如有侵权请联系删除！我们将竭诚为您提供优质的文档！J)If nothing else,the situation has given my college son and me something to share.When I asked his opinion onthis matter,he responded,I like in-class exams because the time is already reserved,as opposed to using myfree time at home to work on a test,he responded.It seems to me that a compromise would be receiving theexam questions a day or two in advance,and then doing the actual test in class with the ticking clock overhead.K)Better yet,how about what one Hunter College professor reportedly did recently for her final exam:She encouraged the class not to stress or even study,promising that,It is going to be a piece of cake.When thestudents came in,sharpened pencils in hand,there was not a blue book in sight.Rather,they saw a largechocolate cake and they each were given a slice.36.Elderly students find it hard to keep up with the rapid changes in education.37.Some believe take-home exams may affect studentsperformance in other courses.38.Certain professors believe in-class exams are ultimately more helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often find the exams more difficult than they actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on the type of course beingtaught.44.The author dropped out of college some forty years ago.45.Some students think take-home exams will eat up their free time.Section C Directions:There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage One Questions 46 to 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the fast-night effect.If a person stays in the same room the following night they tend to sleep more soundly.Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr.Sasaki knew the first-night effect probably has something to do with how humans evolved.The puzzle was what benefit would be gained from it when performance might be affected the following day.She also knew from previous work conducted on birds and dolphins that these画mals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators(捕食者）.This led her to wonder if people might be doing the same thing.To take a closer look,her team studied 35 healthy people as they slept in the unfamiliar envirorunent of the universitys Department of Psychological Sciences.The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains.Dr.Sasaki found,as expected,the participants slept less well on their first night than they did on their second,taking more than twice as long to fall asleep and sleeping less overall.During deep sleep,the participantsbrains behaved in a similar manner seen in birds and dolphins.On the first night only,the left hemispheres(半球）of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding envirorunent,Dr.Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly 6

keep guard in a strange environment,then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones.This is precisely what she found.46.What did researchers find puzzling about the first-night effect?A)To what extent it can trouble people.B)What role it has played in evolution.C)What circumstances may trigger it.D)In what way it can be beneficial.47.What do we learn about Dr.Yuka Sasaki doing her research?A)She found birds and dolphins remain alert while asleep.B)She found birds and dolphins sleep in much the same way.C)She got some idea from previous studies on birds and dolphins.D)She conducted studies on birds and dolphinssleeping patterns.48.What did Dr.Sasaki do when she first did her experiment?A)She monitored the brain activity of participants sleeping in a new envirorunent.B)She recruited 35 participants from her Department of Psychological Sciences.C)She studied the differences between the two sides of participants brains.D)She tested her findings about birds and dolphins on human subjects.49.What did Dr.Sasaki do whe
